Freescale imx7d ADC bindings
The devicetree bindings are for the ADC driver written for
imx7d SoC.
Required properties:
- compatible: Should be "fsl,imx7d-adc"
- reg: Offset and length of the register set for the ADC device
- interrupts: The interrupt number for the ADC device
- clocks: The root clock of the ADC controller
- clock-names: Must contain "adc", matching entry in the clocks property
- vref-supply: The regulator supply ADC reference voltage
Example:
adc1: adc@30610000 {
compatible = "fsl,imx7d-adc";
reg = <0x30610000 0x10000>;
interrupts = <GIC_SPI 98 IRQ_TYPE_LEVEL_HIGH>;
clocks = <&clks IMX7D_ADC_ROOT_CLK>;
clock-names = "adc";
vref-supply = <&reg_vcc_3v3_mcu>;
};
